摘要: 水文周期预报是水资源管理的重要内容,针对西南高原山地区域径流变化差异大特点,本文以云贵高原洒渔河流域为例,根据上中下四个站点1954~2013年径流资料,采用小波分析法对径流变化特征进行研究。研究表明:区域径流第一主周期表现为一致性(四个站点第一主周期均为18 a),显示了大气环流是影响区域径流主周期变化的重要因素;区域径流的第二主周期变化存在明显的差异性(新街站和祖家坝闸站为28 a,而渔洞和黑石罗为11 a),显示了高原山地对径流波动的重要作用;因此采用第一主周期叠加第二主周期长短结合的方法,对于高原山地径流水文周期预报具有较好的作用和意义。
Abstract: Hydrological cycle forecast is an important part of water resources management. For the characteristics of runoff variation in the mountainous area of the southwest plateau, this paper takes the sprinkler river basin in the Yunnan-Guizhou Plateau as an example. According to the runoff data on the four sites in 1954~2013, this paper studies the characteristics of runoff variation. The results show that: the regional runoff first cycle shows consistency (the first main period of the four sites is 18 a), indicating that the atmospheric circulation is an important factor affecting the main cycle variation of the regional runoff; the second period of change of regional runoff has obvious differences (the period of Xinjie station and Zujiabazha station is 28 a; that of Yudong station and Heishiluo station is 11 a), showing the important effect of plateau mountain on runoff fluctuation. Therefore, the method combining the first main cycle and the second main cycle is used, which has a good effect and significance for hydrological cycle forecast of the plateau runoff.
